Flow Behavior and Microstructure Characterization of 7085 Aluminum Alloy Under Various Deformation Conditions

Thermal forming can improve the formability of Al alloy, but researchers do not thoroughly understand the effect of deformation parameters on the flow stress and microstructure evolution of die-casting 7085 Al alloy. In this study, we simulated compression with a Gleeble-3800 thermal simulator between 523 K and 723 K, and strain rates from 0.001 to 1 s−1. We established an Arrhenius flow stress constitutive equation of the alloy. We were...
